摘要
介绍了中国铜的生产、消费及铜矿资源状况,分析了利用废杂铜资源的必要性,指出了研究我国铜循环的重要性。从铜的生产、铜制品的加工制造、铜制品的使用和废杂铜的回收等四个阶段详细地阐述了铜循环的“STAF″模型,运用此模型分析了中国铜的社会存量变化及其流动状况,得到了2002年的铜流图。由铜流图计算了铜工业的原料自给率、使用废杂铜的比例、矿石指数、铜资源效率和废铜指数等重要指标,我国的这几个指标均不及欧洲国家上个世纪90年代中期的平均水平。针对我国铜循环现状,提出了促进铜工业健康发展的一些建议。
The statuses quo of copper production, consumption and copper ore resources in China were introduced, the necessity of copper scrap's recycling was expounded, and the importance of studying copper cycle was analyzed.The ″STAF″ model was expatiated in detail from the four stages of copper production, copper products manufacture, copper products use and copper scraps reclaim.The social reservoir's variations and flows of copper in China were analyzed by using this model, and the copper-flow diagram in 2002 was given.Some important indexes, such as ″material self-support ratio″,″copper scrap use ratio″,″copper ore index″,″copper resource efficiency″ and ″copper scrap index″, etc were calculated based on the copper-flow diagram.The above indexes were all under the average level of European countries in the metaphase of 1990s.As the contemporary copper cycle in China,some suggestions were put forward in order to promote a healthy development of copper industry in China.
